Abstract: A system for a carrying an item comprises an inner sleeve assembly comprising first and second side panel assemblies and a perimeter panel assembly joined to define a sleeve chamber. The perimeter panel assembly comprises a first resilient member, a second resilient member, and a first elastic member. The first elastic member is arranged to apply a first bias force on the second resilient member to deform the second resilient member. The second resilient member applies a first sleeve chamber force on the first resilient member when the first elastic member deforms the second resilient member. When the item is inserted into the sleeve chamber, the first sleeve chamber force causes the first resilient member to engage the item, thereby holding the item in place within the sleeve chamber.

Abstract: Methods and wheel assemblies for supporting a bag that is tilted and pulled along a surface. A wheel housing, a strut member, a spring member, and a wheel member are provided. The wheel housing is rigidly attached to a bottom edge of the bag. The strut member is mounted within the housing for movement between first and second positions. The spring member is arranged between the wheel housing and the strut member to oppose movement of the strut member from the first position to the second position. The wheel member is rotatably attached to the strut member such that at least a portion of the wheel member extends out of the wheel housing as the strut member moves between the first and second positions. The wheel member engages the surface and rotates to allow the bag to roll along the surface when the bag is tilted and pulled. The strut member is substantially vertically aligned when the bag is tilted and pulled and when the strut member moves between the first and second positions.
